Phosphorization process for baby carriage tubes

Abstract

The invention discloses a phosphorization process for baby carriage tubes and relates to the production field of baby carriages. The phosphorization process comprises the following steps: 1) ultrasonically cleaning a steel tube to degrease the steel tube; 2) washing the degreased steel tube with water and drying; 3) performing rust removal treatment on the steel tube processed in the step 2 by virtue of a physical method; 4) washing the steel tube (processed in the step 3) with water and drying; 5) performing surface conditioning on the steel tube processed in the step 4; 6) performing phosphorization on the steel tube processed in the step 5; 7) passivating the steel tube processed in the step 6; and 8) washing the steel tube (processed in the step 7) with water and drying. The phosphorization process has the advantages that steel tube production steps are optimized, a neutralization step in the phosphorization process is omitted, the phosphorization speed of the steel tube is increased and the corrosion prevention effect of the steel tube is improved.

Description

technical field [0001] The invention relates to the field of baby carriage production, in particular to a phosphating process for baby carriage pipes. Background technique [0002] Stroller is a tool cart designed for the convenience of baby's outdoor activities. There are various models, which are generally provided for children aged 1 to 2. Stroller is the baby's favorite walking vehicle, and it is also the mother who takes the baby. The necessities when shopping on the street not only ensure the comfort of children, but also reduce the burden on parents. Parents don’t have to hold their children in their arms wherever they go as before. Babies are uncomfortable, and adults are tired when holding children. When going upstairs, parents have to hold the child and then twist the baby carriage upstairs, so the baby carriage is required to be light in weight, and usually the child sits in the car, so the baby carriage requires a strong structure.

When going upstairs, parents have to hold the child and then twist the baby carriage upstairs, so the baby carriage is required to be light in weight, and usually the child sits in the car, so the baby carriage requires a strong structure. The advantage of being light but strong, the quality of the steel pipe directly affects the safety of children, the steel pipe phosphating process is an important link that directly affects the quality of the steel pipe, it increases the corrosion resistance of the steel pipe, directly affects the service life of the steel pipe and the safety of children, and the phosphorus The long time of the phosphating process will directly affect the production efficiency of the baby carriage, but the current phosphating process takes a long time, and the phosphating effect is not very satisfactory. The patent of Chinese Publication No. CN103726039A discloses a steel pipe surface phosphating process, which reduces Environmental pollution, low risk and easy operation, but this patent does not simplify the phosphating operation process and enhance the phosphating effect of steel pipes
